Abstract
Arc-over in the cathode ray tube (21) of a digital television receiver produces a large current pulse which, when it discharges via the chassis ground, disrupts the reference ground potentials of other circuitry coupled to the chassis ground. The affected circuitry includes digital data storage elements which may experience random state changes caused by the fluctuating ground potential. The CRT arc-over condition is detected by circuitry (460-466) which applies a pulse to the reset terminal of a microprocessor (440), causing it to restore the potentially corrupted data in the data storage elements using preset data stored in a less volatile programmable read only memory (452).
